Name: Date: Period: Accelerated Motion Practice Can an object accelerate even if its speed is constant? If yes, exactly how would this happen? If the change in velocity occurs in less time, does the magnitude of the acceleration increase, decrease, or remain the same? How much time is required for an airplane to reach its takeoff speed of 77 m/s if it starts from rest and its acceleration is +8.2 m/s2? A horse runs with an initial velocity of 11 m/s and slows down to 5.2 m/s over a time of 3.1s. What is the acceleration of the horse? An object travels with an acceleration of +6.24 m/s2 for 0.300s. At the end of the motion, the velocity of the object is +9.31 m/s2. What was the initial velocity of the object? Name: Date: Period: A car moves with an initial velocity of 18 m/s, due north. Find the final velocity of the car after a time of 7.0s if a) the car moves with an acceleration of 1.5 m/s2 due north and b) an acceleration of -1.5 m/s2 due south. A truck moves as shown by the velocity-time graph below. Find the average acceleration of segment A, B, and C. Find the average velocity of each segment. Determine during which segment(s) the truck is accelerating, decelerating, and moving with constant velocity. Truck's Motion Velocity (m/s) 12 10 8 6 4 2 0 0 5 10 15 Time (s) 20 25 30
